Make this 3 Phase Inverter

The post discuses the how to make a 3 phase inverter circuit which can be used in conjunction with any ordinary single phase square wave inverter circuit. The circuit was requested by one of the interested readers of this blog.

The Circuit Concept


A 3 phase load can be operated from a single phase inverter by employing the following explained circuit stages.

Basically the involved stages can be divided into three groups:

  • The PWM generator circuit

  • The 3 phase signal generator circuit

  • The mosfet driver circuit

The first diagram below shows the PWM generator stage, it may be understood with the following points:

The Oscillator and the PWM Stage


The IC 4047 is wired as a standard flip flop output generator at the rate of the desired mains frequency set by VR1 and C1. The 555 IC is configured as a PWM generator which sets the RMS of the 4047 output to the required degree by chopping the output transistor base signals.

The dimensioned push-pull PWM now becomes available at the E/C junction of the two BC547 transistors.
This PWM is applied to the input of the 3 phase generator explained in the next section.



The following circuit shows a simple three phase generator circuit which converters the above input push-pull signal into 3 discrete outputs, phase shifted by 120 degrees.

These outputs are further bifurcated by individual push-pull stages made from a NPN/PNP transistor stages. These 3 discrete  120 degree phase shifted, push pull PWMs now become the feeding input signals (HIN, LIN) for the final 3 phase driver stage explained below.

This signal generator uses a single 12V supply and not a dual supply.

Complete explanation can be found in this 3 phase signal generator article



The circuit below shows a 3 phase inverter inverter circuit stage using H-bridge mosfets configuration which receives the phase shifted PWMs from the above stage and converts them into corresponding high voltage AC outputs for operating the connected 3 phase load, normally this would be a 3 phase motor.

The 330 high voltage across the indivdual mosfet drivers sections is obtained from any standard single phase inverter integrated across the shown mosfets drains for powering the desired 3 phase load.

Full-Bridge Circuit using 3 Half-Bridge Drivers




UPDATE

ISSUES FOUND IN THE ABOVE  3 phase inverter circuit design

The above circuits are not entirely correct and needed a few serious corrections.

After reassessing the circuits I have come up with the following revised diagrams of a 3-phase inverter circuit.

Presently it's a square wave type, I'll soon explain how it could be converted into a modified pure sine wave simply by inserting a dimesioned PWM input to the shut down pins of the half bridge driver ICs.

The ground rail of all the circuits should be terminated into a common line.

4047 3 phase Inverter Circuit

3-Phase Generator Stage


3 phase signal generator


The 3-Phase Full-Bridge Driver Stage






In the above 3 phase generator circuit (second last diagram) using a sine wave doesn't make sense because the 4049 would ultimately convert it into square waves, and moreover the driver ICs in the last design employ digital ICs which will not respond to sine waves.

Therefore a better idea is to use a 3 phase square wave signal generator for feeding the last driver stage.

You may refer the article which explains how to make a 3 phase solar inverter circuit for understanding the 3 phase signal generator stage functioning and implementation details.

Using IC IR2103


A relatively simpler version of the above 3 phase inverter circuit can be studied below, using the IC IR2103 half bridge driver ICS. This version lacks the shut down feature, therefore if you do not wish to incorporate the shut down feature, you can try the following simpler design.

3 phase inverter using IC IR2103(S)PBF

Simplifying the Above Designs


In the above explained 3-phase inverter circuit, the 3-phase generator stage looks unnecessarily complex, and therefore I decided to look for an alternative easier option for replacing this specific section.

After some searching I found the following interesting 3 phase generator circuit which looks pretty easy and and straightforward with its settings.



Therefore now you can simply replace the earlier explained IC 4047 and the opamp section entirely and integrate this design with HIN, LIN inputs f the 3 phase driver circuit.

But remember you will have to still use the N1----N6 gates between this new circuit and the full bridge driver circuit

  1. Hi, Yes some of your points are correct, I'll reassess the above designs and look for appropriate solutions and update them soon..

    ReplyDelete
  2. Done....I have updated the corrected versions, all the issues have been addressed correctly (hopefully).

    ReplyDelete
  3. Hi, maybe the High Frequency PWM signal from the 555 can be applied (through the diodes) to the outputs of the Hex Buffers, so it can quickly turn on/off the square wave signals.

    ReplyDelete
  4. No, that would cause oppostie responses for the NOT gate inputs....it would be more correct to connect the diodes with the shut down pins of the half bridge driver ICs, in fact diodes won't be required, pin#3 of the 555 astable could be directly integrated with the shut down pins of the driver ICs.

  5. Hi i think this circuit will be good for me i would like use for 3 phase 400 volt asynchronus motor as generator for make induction in motor to generating electricity , my aim is from 12 DCvolt engine alternator who spin asynchronous motor convert to 12 v ac and with transformer make 400 v AC an this 400 ac to VDC I dont want use capacitors use between faces for that i would like electronic circuit i am little confuse thats pins SD where i should connect it ?

    ReplyDelete
  6. Hi, the above circuit is a 3 phase motor driver circuit from a single phase source.....so i cannot figure out how it would help your application.

    SD should connected to positive for normal operation, if it's connected to ground the whole IC freezes.

  15. With the value of a few component i'm lost:

    1). R1, P1 from the square wave generator?
    2). rectifier bridge used for the supply of the motor
    3). the driver transistors

    Thanks

    ReplyDelete
  16. 1) R1 and P1 will need to be determined by experimenting as per the desired output frequency.

    2) rectifier diode current will depend on the amp specs of the motor.

    3) you can use IRF840 for the mosfets.

  31. Hello sir I've foud your post ver6 useful to me but a little confused you'd used 555 timer with first 4047 but in after corection you didn't add 555 timer.....why......thank again for such useful post

    ReplyDelete
  32. Thank you Muhammad, the 555 IC stage is for inserting PWM into the inverter in order to make the waveforms modified sine waves,

    I did not include it in the revised diagram just to keep it simple, you can add it if you want across the HIN, LIN inputs of the driver IC.

    ReplyDelete
  33. Dear Sir,
    Can only LM555 be used for PWM instead of 4047 at all. is the output of 4047 in sine form or square waves.

    ReplyDelete
  34. Dear Debu, yes IC 555 can be used instead of the shown 4047...good suggestion thanks!

    4047 has a square wave output

    ReplyDelete
  35. Sir ow we convert 555 square output to Sine Wave

    ReplyDelete
  40. Hello Neeta, I can't produce the calculation for the proposed circuit, since the design is a square wave inverter and the stages are all digital I don't think the dqo transformation would be relevant, even if it is so I have no idea how to do it for the presented design.
    my email can be found in the contact page, at the top

    ReplyDelete
  41. Please sir
    Where do I connect shutdown pin to??

    ReplyDelete
  42. shut down pin can be left unconnected, it must be used only if an automatic output correction is required or for any similar protection switching.

    Thank you for this guide, Super helpful.

    ReplyDelete
  55. Hello Jacob, the 12V can e used only for powering the IC, the motor voltage will need to be 220V in your case. which must be supplied at the drains of the mosfets. No other changes would be required

  59. sir, i'm making a three phase inverter. So far I have made a simple gate driver circuit and I can switch each individual IGBT perfectly. But while making three legs of the inverter how should I connect them. Should I use bootstrap capacitor?

    ReplyDelete
  60. Amit, you will have to make an ordinary single phase inverter, then rectify its 330V AC to 330V DC and use it with the full bridge circuit for getting the required three phase output....the 3 phase from the mosfet/IGBT bridge can be directly used for operating the 3 phase load

  81. It's my pleasure Pathmasiri, that looks like a beautiful and very simple to implement IC, I'll definitely introduce this chip in my website soon, through a new article.

    By the way you just have to apply an alternating 3 phase signal across the shown LIN HIN inputs of the IC, exactly as explained in the above article.....and you can get the results by directly connecting your motor across the shown outputs since it already incorporates built in mosfets.

    ReplyDelete
  115. Hi Abhishek, sorry what are you trying to make with the opamps? are you trying to make the 3-phase generator?...you will have to check/confirm each and every stage separately, very carefully and with full understanding otherwise you can never succeed...this project is for the experts who have advanced knowledge of electronics, so proceed with caution

    ReplyDelete
  116. Good morning, I'm sorry for the posting of the article. I have a question with this circuit, how can I reverse this engine?

    ReplyDelete
  117. for reversing the motor, you can reverse the 3 phase sequencing through a TPTT switch or 3 pole 3 way switch connected across the HIN, LIN inputs

    ReplyDelete
  118. Good morning, Mr. Swagatam, thanks for the help in the engine reversal !!
    but I have another doubt I would use the circuit with a three-phase network could explain how the circuit would be because the three-phase simulator would be removed and would be only the ckt pwm and the high voltage

    ReplyDelete
  119. Good morning Bruno, you can remove the entire 3phase generator stage and feed the HIN and LIN with rectified DC from the available 3 phase supply.

    you can use resistive divider network for dropping the high 3 phase signal into 12V low voltage 3 phase signal and feed them across the HIN LIN inputs.

    ReplyDelete
  120. Thank you master, see if you're sure I'll do it okay.
    1 calculate the resistor oara the voltage drop from 120 vac to 12 dc
    2 put a rectifier diode on the end of each phase then I'll enter the gates of ci 4049 for the alteas and low entrances ok ??

    ReplyDelete
  121. That's right Bruno, but after rectification to 12V DC the extra rectifier diodes will not be required.

    ReplyDelete
  122. make sure to have 3 DC inputs sequencing alternately as per the 3-phase signal

    ReplyDelete
  123. Good morning sir I doubt in the three-phase generator circuit I saw that it found a simpler circuit in its searches I would like to know where I would enter the pwm pulse generator made with c i 4047

    I can use the original circuit that you did with the ci 324 it works correctly ???

    ReplyDelete
  124. Good Morning Bruno, the PWM pulse will need to be inserted to the low side mosfets, it cannot be inserted to the IC 4047 stage....first try the LM324 generator separately if you succeed then you can proceed.

    ReplyDelete
  125. sir, I have seen a new diagram that you have designed, you can see that you do not need the ci 4049 to make the high and low outputs in the inverter design. I'm going to try this new circuit. the lady changed the ci before was an ir2110 now I see an ir2103 has any difference between them tks

    ReplyDelete
  126. Lord I'm sorry for writing because I'm Brazilian and we talked through translation on LINE so there may be difficulty understanding the words okay good night

    ReplyDelete
  127. Bruno, It may work without 4049 but it is recommended for accurate functioning of the circuit, because the driver IC is a digital IC, therefore the input signals must be also perfectly digital or logical.

    The two ICs are exactly similar, but IR2103 is the simpler version and it does not have the shut down pin, the IR2110 has the shut down pin option, so if you do not wish to include shut down feature, then IR203 can be used.

  128. Dear sir, I have need a 24v dc to 400v ac 50 Hz 2kw inverter for induction motor. How possible to get it. There is a mosfet drive 3 phase inverter that you have given. May I use this circuit for my demand ? If possible, which quality mosfet need for output 400v ac / 2kw. Sir please help me. Thanks. Aristarcus.

  129. Hi Aristarcus, yes you can use the circuit for driving any 3 phase motor, just make sure the mosfets are appropriately rated as per the motor ratings

  130. Sir what i do
    Power driver ic2103 and any driver ic
    Are not available in the market

    Sir please give any other ic solution for three phase inverter 12v dc to 240v AC

  131. Abhishek, just Google "half bridge driver IC" you will be able to find many.

  132. Sir
    What is working of h bridge driver ic
    After three phase generations stage
    Why I can't give these to mosfet
    Please tell me sir and working of h bridge driver ic

    ReplyDelete
  133. The driver IC performs complex processing for activating the high side mosfets, necessary for operating a full bridge network...without these operations a full bridge cannot work

  134. Can I use 33883 ic is a h-bridge driver ic
    In respect of other half bridge driver ic
    Please sir I am very upset

    ReplyDelete
  135. yes definitely you can use it....

  136. Sir how connect this
    HIN and LIN in which pin
    Sir can you provide the diagram
    So kind sir

    ReplyDelete
  137. Abhishek,
    you will have to make a 3-phase generator circuit first and then feed the 3 phase signal to the HIN, LIN inputs of the IC.

    ReplyDelete
  138. Sir I'm already complete three phase signal generations stage
    But problems sir how connect HIN and LIN in which pin of 33883ic
    Because thise is the new ic
    Only one ic use or three ic use or how is as full bridge driver

    ReplyDelete
  139. I am sorry, your IC is not a 3 phase driver, it is only a full-bridge driver IC, I mistakenly assumed it to be a 3 phase...if you are trying to search for 3 phase driver IC, then you must Google "3-phase driver IC"

    By the way I had told you to search for a "half bridge driver IC" not full bridge IC...so please search for alternative "half bridge driver ICs" and then you can use 3 of these ICs to build a 3 phase inverter by integrating a 3 phase signals

  140. hello can I use SG 3524 ic in the 3phase circuit with ir2110 can it work for me better thanks

    ReplyDelete
  141. sorry that may not be possible..

    ReplyDelete
  142. Hello this inverter how many watt?

    ReplyDelete
  143. The wattage can be any desired value depending on the rating of the mosfets and the input current
